6 ALARM / STATUS PARAMETERS
6.1 GENERAL
Bronkhorst digital instruments have a build in alarm function. It is used to indicate several types of alarms:
System errors
System warnings
Min/max alarms
Response alarms
Batch alarm
Master slave alarms
The alarm can be read out using parameter alarm info. After an alarm a setpoint change can be set. This means the
setpoint will go to the set value after an alarm occurs. A delay can be set to prevent reaction to glitches in
measurement or power. How an alarm can be reset is controlled by the parameter “reset alarm enable”. It can bit-
wise be set to automatic, reset, external or keyboard/micro-switch. After the reset the alarm stays present during the
alarm delay time. In the functional schematic below the basic alarm function is explained.
